When to throw away brass

What signs do I need to look for to determine when to throw my brass away? I have Remington cases in 300rum. They have been loaded 3 times FL and the primer pockets seem really loose on some cases. I loaded them up for a 4th times and was very careful and I didn't have any soot around the primers. My guess would be that I need to chunk them now and get new ones.

I pretty much use brass until it destroys itself. Use once fired for hunting and all the important stuff and everything else for practice. The latest 100 is on the third go around and they are perfect. All of this is with a -06 which may not be as hard on brass as a 300rum. Leakage around the primer would be a sign that things aren't going good. You should get much more than four firings though.

I shoot them till the primer pockets will not hold a primer unless I start feeling case head groove or getting split necks, If that happens I retire the hole batch. P.S. 300 rum brass will give out in the primer pockets first, you can kill the primer pocket in one firing of a real hot load without having any other sign of pressure.

I'm with Jim on shooting them until they give up. If the primer pockets are truly loose after 3 loadings you are loading too hot. Need to tune it down a bit. Cutting case life more than half for a 1% or 1.5% gain in velocity is something most all of us get over. If you are asking if you need to thow away cases then it is very unlikely you are to the point in shooting range that 30 to 50 fps will affect anything but your feelings. I think most of us pushed the loads really hot when we start but get tired of buying powder and brass for nothing. If there was no signs other than the primers go in easy I would load them again. $110.00 + shipping a hundred is a bunch of green to just throw away.

Some brass and loads seam to last forever and some dont!! I've got some hot loaded 223 & 243 brass that is past 10 reloadings......Ya its getting tired and only the LC and Winchester brass made it that far, the Federal cases fell out after a couple reloadings due to primer pockets letting go and the Remington cases split necks between 4-5-6 reloadings.
I just tossed all but 10 of my 338 Edge(neckt up 300RUM) brass after 3 reloadings=The primer pockets where toast! I could understand if it was Federal brass but I expect more from Remington!
